Radiative corrections to the reggeized quark-reggeized quark-gluon effective vertex

This paper is devoted to the calculation of the reggeized quark-reggeized quark-gluon effective vertex in perturbative QCD in the next-to-leading order. The case of QCD with massless quarks is considered and the correction is obtained in the D→4 limit. This vertex appears in the quark reggeization theory, which next-to-leading order extension is now under construction.
